Rod mills are very similar to ball mills, except they use long rods for grinding media. The rods grind the ore by tumbling within the the mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6. Rod mills accept feed up to about 50 mm (2 in.) and produce a product in the size range of 3000 to 270 mm (4 to 35 mesh).Rod mill is widely applied in metal and nonmetal mine, water conservancy, glass and construction materials industries, mainly suitable for grinding various ores and rocks and artificial sand-making.
General Kinematics VIBRA-DRUM Grinding Mills are proven in dozens of milling applications in the mining and mineral industries. Because of this flexibility, they are the perfect solution for your needs, no matter the grinding processes you use.
Each grinding mill is achieving impressive energy savings (35-50%), thanks to a unique rotational material motion that is more efficient than conventional ball or rotary grinding mills. New processes such as micron grinding and mechanochemical grinding give our customers a unique and effective competitive advantage.
VIBRA-DRUM Grinding Mill units are also ideal for continuous processing of difficult-to-fluidize products such as large flake and stringy or tacky materials. Typical VIBRA-DRUM Grinding Mill applications include direct gas contact heating, drying, cooling, and coating. Need more information about the General Kinematics VIBRA-DRUM Grinding Mills?

The capital cost of a VIBRA-DRUM Grinding Mill is significantly less than a rotary grinding mill containing a comparable media load. Some of the VIBRA-DRUM Grinding Mill features to keep installation costs low include:
Minimal moving parts and innovative engineering combine to provide you with a grinding mill that requires little maintenance and downtime requirements. The maintenance of the VIBRA-DRUM products is simple and consists of:
Exceptional grinding performance and energy savings are the result of the VIBRA-DRUM natural frequency design. A sub-resonant, two mass drive and spring system alternately stores and releases grinding power. Once in motion, energy is only needed to move the grinding media as a fluid mass, and to overcome frictional losses.
The increased number of impacts in our VIBRA-DRUM Grinding Mills result in a faster, more efficient grinding action. As the grinding mill vibrates, media particle migration is experienced in both axial and transverse directions. In fact, the media migrates through the VIBRA-DRUM Grinding Mill in a path similar to that of a rotary grinding mill without lifters, but each media particle imparts positive impact energy at each vibration.
The area where comminution takes place is larger and more efficient compared to a rotary grinding mill of similar size. There are no dead zones of inactive media inside the vibrating grinding mill. And, unlike stirred or tower grinding mills which grind by attrition, the VIBRA-DRUM Grinding Mill uses the principle of impact grinding which causes clean breaking and doesnt coat the mineral/gangue with slimes.
VIBRA-DRUM Grinding Mills excel over conventional ball, stirred media, or vertical roller mills in both grinding and energy efficiency. The features listed below highlight why our mills are so effective and efficient.
The capabilities of the VIBRA-DRUM Grinding Mill are unmatched. Extensive in-house or on-site testing is available to qualify your product requirements. General Kinematics also offers wet or dry particle analysis as well as access to our on-staff material scientist for further material qualification.

Applications: It is mainly used in the processing of fine powder and ultrafine powder in metallurgy, mining, building materials, chemical industry, refractory materials, abrasives, graphite, glass, ceramics and other industries.
Vibration ball mill, also known as a vibrating ball mill or vibratory ball mill, is a kind ofball mill machinethat uses the high-frequency vibration of the cylinder to make the grinding medium in the cylinder impact the material by inertial force.
Vibration ball mill is a new type of high-efficiency and energy-saving grinding equipment. It has obvious advantages over traditionalrotary ball millin grinding fine and ultra-fine powder materials. The grinding efficiency of vibrating ball mill can be increased by 2-5 times, and energy consumption can be reduced by 20% 30%.
Vibration ball mill can be widely used in fine powder and ultrafine powder processing in ore dressing, building materials, abrasive materials, chemical raw materials, metallurgy, electric power, special ceramics, refractory materials and other industries. In recent years, the vibration mill has been widely used in the magnesium industry because it solves the problem of powder sticking and grinding in the production process.
When the vibratory ball mill is in operation, the motor drives the vibrator with the eccentric hammer to do the axial rotation motion, which causes the barrel to vibrate. The medium and materials are turned and dropped in the barrel, and the materials are crushed under the impact force.
As a ball mills supplier with 22 years of experience in the grinding industry, we can provide customers with types of ball mill, vertical mill, rod mill and AG/SAG mill for grinding in a variety of industries and materials.
